The 2022 Acura Trucks RDX sits firmly in the modern luxury crossover space, blending sharp styling, everyday utility, and the kind of athletic road manners that make tire choice more noticeable than on a softer, comfort-only SUV. For this exact RDX, fitment centers on two primary radial sizes: 235/55R19 and 255/45R20, with the correct choice tied directly to sub-model and wheel diameter. That means the real decision is not just brand selection, but also whether your RDX carries the 19-inch or 20-inch setup and what sidewall treatment or tire series best suits its look and use. A careful match preserves both stance and drivability.
Which Tire Size Is Right for The 2022 Acura Trucks RDX
The 2022 Acura Trucks RDX uses two primary tire sizes, and the difference comes down to sub-model and wheel diameter. Some versions use 235/55R19 on a 19-inch rim, while others use 255/45R20 on a 20-inch rim. Before choosing a tire, confirm the exact sub-model and make sure the vehicle still has its intended wheel package, since 19-inch and 20-inch fitments are not the same decision.
Fit(s): A-Spec, SH-AWD A-Spec, and SH-AWD PMC Edition
Construction: Radial|Rim: 20 in
255/45R20 is a modern metric radial size in which 255 identifies the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter in inches. On the 2022 Acura Trucks RDX, this size is tied to the 20-inch wheel package used on certain sub-models. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with Blackwall, raised white letter, and Redline sidewall treatments represented. This size is worth evaluating when the vehicle carries the larger-wheel appearance and the buyer wants to compare both performance-oriented series and visual presentation.
235/55R19 is a modern metric radial size, with 235 describing nominal section width in millimeters, 55 showing the aspect ratio, R marking radial construction, and 19 identifying the wheel diameter in inches. On the 2022 Acura Trucks RDX, this size applies to several sub-models built around the 19-inch wheel setup. Its role in the lineup is straightforward: it is the correct primary fitment for those configurations rather than an alternative to the 20-inch package. Buyers should confirm the actual wheel diameter on the vehicle before moving ahead, especially if wheels have ever been changed.
Tire fitment for the 2022 Acura Trucks RDX varies by sub-model, so identifying the exact trim is the first step before comparing tire options. The main split is between 19-inch and 20-inch wheel packages, which means size selection is tied directly to the version of RDX in front of you.

The 2022 Acura Trucks RDX Base uses the 235/55R19 radial size associated with the 19-inch wheel package. For this sub-model, the key is staying with the proper 19-inch fitment rather than assuming interchangeability with the 20-inch A-Spec-style setup.

The 2022 Acura Trucks RDX SH-AWD PMC Edition uses the 255/45R20 radial size. Tire selection for this version is driven by the 20-inch wheel package, so visual style and series choice matter only after the wheel diameter and overall setup are confirmed.

Tire Size & Fitment
What tire size fits a 2022 Acura Trucks RDX?
The 2022 Acura Trucks RDX uses two primary tire sizes: 235/55R19 and 255/45R20. The correct size depends on the sub-model and its wheel package, with several trims using the 19-inch fitment and A-Spec-related versions using the 20-inch fitment.
That means the first step is confirming exactly which RDX trim you have and checking the wheel diameter actually on the vehicle. An RDX that has had wheel changes, accessory packages, or replacement wheels should be verified in person before selecting tires, because the 19-inch and 20-inch fitments are separate applications.
What size rim does a 2022 Acura Trucks RDX use?
A 2022 Acura Trucks RDX uses either a 19-inch or 20-inch rim, depending on sub-model. The 235/55R19 tire size belongs to the 19-inch wheel setup, while 255/45R20 belongs to the 20-inch wheel setup used on certain trims.
Rim diameter is the key fitment checkpoint on this RDX because neither tire size crosses over to the other wheel diameter. Check the tire sidewall and the wheel itself before ordering replacements, especially if the vehicle was purchased used or has been upgraded with different wheels for appearance or seasonal driving.
Do all 2022 Acura Trucks RDX sub-models use the same tire size?
No, 2022 Acura Trucks RDX sub-models do not all use the same tire size. Base, SH-AWD, Tech Pkg., SH-AWD Tech Pkg., and SH-AWD Advance Pkg. models use 235/55R19, while A-Spec, SH-AWD A-Spec, and SH-AWD PMC Edition models use 255/45R20.
That split matters because tire selection starts with the trim level, not just the model name on the tailgate. An RDX owner who assumes every version uses the same tire can easily end up comparing the wrong products, so matching the sub-model to the actual wheel package is the safest starting point.
Choosing the Right Tire
What should I consider when choosing a tire for a 2022 Acura Trucks RDX?
Start with the correct primary size for the exact 2022 Acura Trucks RDX sub-model, since this vehicle uses either 235/55R19 or 255/45R20. From there, compare construction, wheel compatibility, brand, sidewall style, and any available load or rim-width details that matter for how the vehicle is actually used.
A buyer with a 20-inch RDX fitment may also care more about series character and sidewall presentation, since Blackwall, raised white letter, and Redline options are available in 255/45R20. The right choice comes from matching the tire to the vehicle's wheel setup, intended appearance, and normal road use rather than picking by brand name alone.
What sidewall styles are available for 2022 Acura Trucks RDX tires?
For the 2022 Acura Trucks RDX in 255/45R20, available sidewall styles include Blackwall, raised white letter, and Redline. Those choices give the larger-wheel RDX fitment a wider visual range, from a modern understated look to a more expressive performance-style presentation.
Sidewall style changes appearance more than fitment, but it still needs to be selected within the correct tire size and wheel diameter. A buyer choosing between 20-inch products should decide whether the goal is a clean late-model look or a more distinctive visual accent, then confirm the rest of the tire specifications still suit the vehicle.
What brands offer tires for the 2022 Acura Trucks RDX?
The 255/45R20 fitment for the 2022 Acura Trucks RDX is available from BFGoodrich, Nitto, and Pro-Trac. Those products span several radial series, including BFGoodrich g-Force lines, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand choice should be part of a larger comparison rather than the only deciding factor. Once the correct size and wheel diameter are confirmed, it makes sense to compare each tire's series, sidewall styling, and any stated rim-width or load details so the final choice suits both the RDX setup and the owner's priorities.
Restoration & Appearance
Which tire should I choose for a period-style 2022 Acura Trucks RDX?
A 2022 Acura Trucks RDX is a modern luxury crossover, so a period-style choice usually means keeping the vehicle visually consistent with its original era rather than recreating a vintage tire look. The right starting point is the correct factory-era size for the sub-model, either 235/55R19 or 255/45R20.
Appearance decisions make the most sense after size and wheel diameter are locked in. On 255/45R20 applications, sidewall treatment can noticeably change the look, while owners focused on a clean late-model presentation may prefer a simpler sidewall style that matches the RDX's contemporary design language.
Which sidewall style suits a period-style 2022 Acura Trucks RDX?
For a 2022 Acura Trucks RDX using 255/45R20, Blackwall generally gives the most understated contemporary appearance, while raised white letter and Redline add a more customized visual statement. Each can suit the vehicle, but they create very different impressions on a modern crossover.
The best match depends on whether the goal is a clean showroom-era look or a more personalized stance. Sidewall style should never override correct fitment, so choose it only after confirming the proper sub-model size and wheel package, then decide how prominent you want the tire to be in the overall appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2022 Acura Trucks RDX?
Yes, modifications can affect tire fitment on a 2022 Acura Trucks RDX. Wheel changes, altered offsets, lowering, suspension work, or body changes can all influence how a 235/55R19 or 255/45R20 tire sits in the wheel opening and how much clearance remains during steering and suspension travel.
That is especially important on an RDX because the model already uses two distinct wheel diameters across its sub-models. A vehicle with aftermarket wheels should be checked for actual rim diameter, width, and clearance at the fender and suspension before assuming a replacement tire in the stock-size format will still suit the setup.
What should I inspect before driving a 2022 Acura Trucks RDX on new tires?
Before driving a 2022 Acura Trucks RDX on new tires, inspect the wheels for damage, confirm the installed tire size matches the vehicle's wheel package, and look over inflation, valve stems, and basic mounting condition. A quick visual check for sidewall damage or bead issues is also worthwhile before regular road use.
Once the tires are on the vehicle, pay attention to clearance at full steering lock and during normal suspension movement, especially if the RDX has non-original wheels. It also helps to recheck air pressure after initial use and watch for vibration or uneven behavior that could point to balance, alignment, or fitment concerns.
How often should tires on a 2022 Acura Trucks RDX be inspected?
Tires on a 2022 Acura Trucks RDX should be inspected regularly, not just when they look worn. Frequent visual checks for uneven tread wear, cuts, bulges, punctures, and air loss are important, and low-mileage vehicles still need attention because age and storage conditions can affect tire condition over time.
Monthly pressure checks are a sensible habit, and an inspection before longer trips is especially useful on a crossover that may see highway driving and changing cargo loads. Owners should also take a closer look after pothole impacts or wheel changes, since those events can alter alignment or reveal fitment issues that were not obvious earlier.
